Yep, it makes good sense for me too! Now it would be interesting to
see if we can obtain better timing results if we let the reactor
process incoming data while still scheduling.

I think I'll continue with this kind of inspection since it seems to
be an easy way to obtain data about how the various pieces work
together in VIFF.
